What should I do if the motorcycle consumes high fuel?

Generally speaking, the law of locomotive fuel consumption is: two-stroke engine is higher than four-stroke engine, large displacement is higher than small displacement, and female scooter is higher than male straddle-type vehicle; In addition, different engine structures have different fuel consumption. Users can judge whether the fuel consumption is too high according to their own models, roads and driving differences between suburbs and urban areas. The scooter with the specific value of 70- 125ml is about 3.5L; Among them, carburetor is the key component of motorcycle fuel supply system, and its good condition is very important to the fuel consumption of the whole vehicle.

At present, reducing fuel consumption is the goal pursued by various manufacturers, which can save energy and reduce air pollution. Therefore, this paper introduces the causes of high oil consumption and the methods of saving oil:

First, the reasons for high fuel consumption:

1, the gasoline number used is too low or too high;

2. There is oil leakage and oil leakage in motorcycle oil circuit;

3. The motorcycle running system has too much resistance;

4. Incorrect ignition time (premature or delayed);

5, the engine cylinder pressure is insufficient;

6. Improper adjustment of carburetor (high oil level in buoy chamber).

Second, the method of saving fuel:

1. Prevent oil leakage: The fuel tank, fuel tank switch, oil pipeline and chemical pipeline of motorcycle should be inspected frequently to prevent oil leakage and oil leakage.

2. Maintain a good idle speed: the idle speed should not be too high, otherwise it will increase fuel consumption, but it should not be too low; If the engine is too low, it will run unsteadily and turn off easily, so it should be adjusted strictly according to the requirements of the manufacturer.

3. Don't step on the accelerator: After the motorcycle starts to heat up, don't step on the accelerator; This will not only accelerate the wear of parts, but also cause a waste of fuel.

4. Ensure the normal ignition system: When the engine ignition system fails, it will cause insufficient combustion, slow acceleration and weak fuel consumption.

5. Correct adjustment of carburetor: mixed steam should not be too rich or too thin. If it is too thick, the fuel will not be completely consumed. If it is too thin, the engine power will be seriously reduced and the fuel consumption will increase. In use, the carburetor can only be adjusted repeatedly to save fuel.

6. Choose the right gasoline: The higher the gasoline number, the better it will be used on motorcycles with high compression ratio. Because the higher the gasoline number, the higher the ignition point, the lower the gasoline number and the lower the ignition point. Therefore, when choosing gasoline, we should choose it according to the model and the local temperature difference. The higher the ambient temperature, the better the gasoline atomization. At this time, high-grade gasoline can be used first, and the lower the ambient temperature, the worse the atomization. At this time, you can choose low-grade gasoline.

7. The tire pressure should be reasonable. Too high or too low tire pressure will increase fuel consumption.

8, pay attention to keep the normal work of the braking system, to avoid resistance and increase fuel consumption due to poor braking.

In addition, the maintenance status of the scooter air filter will directly affect the fuel consumption! Cleaning should be based on mileage, the road conditions are dusty, and the air filter should be cleaned more frequently or replaced with new ones!

What should I do if the motorcycle consumes high fuel?

1 power system. If you want to save fuel, it depends on whether the power efficiency is high (the clearance between cylinder, piston and piston ring, and whether the valve adjustment is reasonable), which seems to be closely related to the oil melting effect of carburetor.

2 Your scooter's brakes are adjusted tightly, which may also increase fuel consumption;

There are many things and heavy things in the storage box of the car itself, and the fuel consumption will obviously be too large.

Suggestion:

1 use fuel consumption software to confirm the actual fuel consumption of your car (the download address of fuel consumption calculation software is: dl.pconline/download/51558, and it can be used after I download it);

Try not to refuel violently when starting, start slowly, and let the combustion of gasoline do as much work as possible.

Under normal circumstances, it's best to ride at a constant speed, don't accelerate and brake suddenly, and change the filter after 3000 kilometers. Change the engine oil and gear oil after several kilometers, driving habits are normal, and do not bring too much load;

Find a better master to repair the original carburetor, adjust the carburetor to the exhaust pipe until there is no black smoke, and then adjust the motorcycle valve to the right position;

If it's not a long-distance ride, don't add too much at a time, just add it to two-thirds of the fuel tank.

Gasoline will volatilize, which is of course related to the temperature near the fuel tank. Try not to refuel at night in winter, because the air humidity is high, and there may be condensed water in the fuel tank when refueling.

Are you sure there are not many impurities in the oil you add?

This new motorcycle consumes a lot of fuel. What is the reason and how to deal with it?

The carburetor is of poor quality. Look for the store to see if it's bad. Buy a good brand car or change the carburetor.

What should I do if the motorcycle consumes a lot of fuel?

The biggest reason for high fuel consumption is road conditions, long-term low speed and high speed, and stop-and-go.

Second, the mixing ratio is too large, so you can consider lifting the oil needle buckle up by one grid. Or make a mark on the mixing ratio screw and then jump off the fuel ratio slightly;

Third, the fuel consumption of an engine with excessive viscosity will be about 5% higher than normal;

Fourthly, using ethanol gasoline, if the ethanol part is directly regarded as not added, the fuel consumption can be reduced by10%;

Reasons for high fuel consumption of motorcycles;

First, increase the throttle in neutral to see if the exhaust pipe smokes. If there is black smoke, it means that the mixture is too thick and consumes oil. It is recommended to clean the air filter and carburetor. And make appropriate adjustments to the carburetor. If there is blue smoke, it means that the oil power of the cylinder string reduces the fuel consumption. It is recommended to replace the piston ring or cylinder. If there is no smoke, try it at high speed. If the engine speed increases, the vehicle speed does not increase as fast as before, indicating that the clutch plate is worn too much and consumes too much oil. It is suggested to replace the clutch plate and steel plate to solve the problem. The premise is that the front and rear wheels of the car have no abnormal resistance, that is, the brakes are not locked and the wheel bearings are operating normally.

What is the high fuel consumption of motorcycles?

If nothing else, just tell you how to save fuel:

How to make your motorcycle more fuel efficient?

An indicator of motorcycle fuel consumption is generally expressed by the actual fuel consumption per 100 kilometers (liters). Every user wants his motorcycle to save fuel as much as possible. If he wants to save fuel, when he starts to buy a motorcycle, he should first consider what kind of motorcycle can meet his fuel economy requirements. Second, we should consider how to drive to save fuel. Third, we should consider what fuel-saving measures can be taken for motorcycle maintenance. Fourth, we should consider the relationship between motorcycle renewal and fuel economy. The following four aspects are described respectively.

First, how to consider the requirements of fuel economy when buying a motorcycle

When buying a motorcycle, we should comprehensively consider various indicators of the motorcycle, such as what kind of road the motorcycle can run, its maximum speed, acceleration, weight, fuel consumption and so on. When there are special requirements for the fuel quantity index, there should also be friendly requirements for other indexes to achieve the fuel economy and a certain level of performance index of the purchased car. So what kind of motorcycle saves fuel and mud?

1. Motorcycles with two-stroke engines are more fuel efficient than motorcycles with four-stroke engines. This is because in a two-stroke engine, at the end of scavenging process and exhaust process, there is always a moment when scavenging holes and exhaust holes are opened at the same time. At this time, it is inevitable that a fresh gas will flow out of the exhaust hole because of short circuit, so that some fuel will be lost without burning, and fuel consumption will increase.

2. The smaller the engine displacement, the more fuel-efficient.

3. The two-stroke engine with reed valve and rotary valve is more fuel-efficient than that with piston valve. This is because both the reed valve and the rotary valve increase the intake phase angle, which makes the intake more sufficient, and at the same time, it also prevents the gas from spraying back, especially at low speed. Most new motorcycles adopt these two air intake modes, such as Yamaha RX 125, reed valve and Suzuki A66.

Second, how to drive to save fuel.

1. The fuel consumption curve of the engine is fishhook-shaped, which belongs to the low fuel consumption area in the middle speed range. Medium speed generally refers to 3000 ~ 4000 revolutions per minute. If it is lower than this speed, the flow rate of mixed gas decreases, which makes the mixing uneven, the combustion becomes bad and the fuel consumption increases. When the speed is higher than this range, in order to give full play to the maximum power of the engine, the carburetor of the engine supplies rich gas, and the fuel consumption will also increase. According to this principle, as long as the speed is often controlled within the range of medium speed, it will inevitably save fuel. The total transmission ratio between the engine and the wheels of a three-wheeled motorcycle is different from that of a two-wheeled motorcycle. The total transmission ratio of three-wheeled motorcycle is 8 ~ 9, that of two-wheeled motorcycle is 5 ~ 6, and the corresponding rotation speed of three-wheeled motorcycle is 3000 ~ 4000 rpm. The speed of the third gear is 20 ~ 30 km/h, and the speed of the fourth gear is more than 40 km/h. The speed of two-wheeled motorcycle is 3000 ~ 4000 rpm, the speed of third gear is 30 ~ 40 km/h, and the speed of fourth gear is more than 50 km/h. The above speeds are in the middle throttle position, so if you want to save fuel, you should avoid using the big throttle and use the middle throttle.

2. Making full use of the inertia of motorcycle when driving can save fuel. One driving situation is that when you want to stop, you only use the inertia of the motorcycle, don't brake, and stop automatically after driving for a while. In another case, when the driver observes an obstacle in the distance ahead, he will slow down in advance and slide in neutral. When the car reaches the obstacle, the speed will be reduced, so it can cope with the emergency, which avoids consuming the energy of the engine through braking and deceleration, so it can save fuel.

3. In long-distance driving, if you want to save fuel, you must master the speed of the motorcycle you use at the lowest fuel consumption. Generally, the minimum fuel consumption of two-wheeled motorcycles is 70 ~ 80 km/h, and that of three-wheeled motorcycles is 45 ~ 50 km/h..

4. Reasonable tire pressure is an important factor for fuel-efficient driving, and motorcycle tire pressure must comply with the specifications. If the air pressure is insufficient, the tire will consume unnecessary energy and increase fuel consumption. Therefore, it is best to check the tire pressure with a barometer before driving, especially before driving for a long distance.

It should be pointed out that some people think that taking a taxi can save fuel, which is wrong. Taxi driving seems to save fuel, but motorcycles must accelerate to a higher speed before they can slide. At this stage, fuel consumption will increase, and on average, it may not save fuel. Besides, it is unsafe to drive a taxi in a crowded place in the city, because the engine can't take part in taxiing ... >>

What is the reason for the high fuel consumption of motorcycles?

Your fuel consumption is not particularly high at the beginning of three liters. Generally, the fuel consumption of GY6 125 engine is like this. If you feel more fuel-efficient than before, check whether the air filter is blocked and need to be cleaned or replaced every 2,000 kilometers. In addition, you usually drive slowly in the urban area, and there are many braking points. The fuel consumption has a lot to do with your driving habits and road conditions.

How to solve the problem of increasing fuel consumption of 1 10 motorcycle?

Check whether the sea speed is too high before changing the carburetor. If so, turn it down. Generally, 700- 1000 rpm is enough, and new cars can be less.

What's the matter with the scooter's sudden increase in fuel consumption?

The first reason: the carburetor concentration ratio is unbalanced, so it is necessary to clean the carburetor or adjust the fog needle! These need to be repaired in the shop.

Master still cleans, but it's no good. He will change a carburetor for you. The price is around 100- 120.

If it is a new car, replace the carburetor within 1 year.

The second reason: you always drive a short distance in the street, such as 2 kilometers, 1 kilometer, keep the speed at a low speed of 20-35, turn off the engine frequently, and so on! Try to shoot a long distance, such as more than 8 kilometers in a row, and keep the speed between 35 and 60. If it still consumes gas, it means that the car really consumes gas! Need to check the car

The third reason: air intake system, if the car is relatively new, there is no need to check the air intake system! Old cars need to check the air filter, that is, the big sponge, to see if there is much dust and need to be cleaned or replaced. Price 10 yuan arrives in 30 yuan!

We often say that the normal fuel consumption index of scooters is as follows: fuel-efficient models-fuel consumption per 100 kilometers is 2.3 liters -2.8 liters 93#

Ordinary car: the fuel consumption per 100 kilometers is 2.9-3.5 liters 93#

Vehicles needing maintenance: fuel consumption per 100 kilometers is 3.6-4.2 93#

The data obtained in the above three cases are all based on the average speed of a person riding, 35-65 speed.

What should I do if the scooter consumes more and more fuel?

Besides changing the oil and cleaning the air filter, you should always check whether the tire pressure is normal. Low tire pressure will also affect fuel consumption. In addition, when replacing the oil filter for maintenance, you should clean the oil nozzle! Pay attention to driving habits. The throttle is very big, and it will definitely cost oil! Moreover, whether the new car runs in well or not will also affect the fuel consumption in the future! ! !

What is the reason for the high fuel consumption of motorcycles?

The odometer is broken? How is the fuel consumption of the landlord calculated?

If it is still 3 after accurate measurement. 5. In view of the fact that the landlord has checked everything that should be checked, the rest can only consider whether there is oil leakage in the fuel tank and carburetor, or whether it is driving in the urban area for a long time, and the fuel consumption is naturally high.
